Be it knownthat I, EDWARD L. Sunny, a

citizen of the United States, and a resident of Wa r ry, n hecounty ofew av n and State of Connecticut, have invented a new and ImprovedEngine, of which the fol- My invention relates more especially to. theclass of engines known as explosive, or gas engines, in which gas isadmitted to they cylinder and then expanded as by exploding with anelectric spark, the force of the ex: plosion r ng e piston- Tlie objectof my invention is toprovide a device of this class-in, which the fullbenefits of -,the force of the explosion may be obtained; and a furtherobject of the invention istO; Provide a device in which th QITCegenerated by the explosion shall be gradually communipated to the drivenmechanism. One form -of device in the use of which these objects may beattained is illustrated in the accompanying drawings, in Which-7'"@Figure 1 isa view in central longitudinal section through the left handcylinder of an en n e o y ng my n t n; the t asfseen in Fig. 5. 2 is abottom view otthe engine, the pistons beingshown in a position reversedtroin that shown in Fig. 1.

Inlets doommunicate with one end of each of the cyllnd'ers, theseinletsextending from. a carbureter, common to this type. of engine, bymeans of gas and air. is supplied. to the chamber 6, ineach of thecylinders. Thecarbureter hasnot been shown in. thedlrawin s as its.locai tion and function will be readi y understood by those skilled inthe art. nals 7, connected with any suitable source of electric energy,are located in each of the ;cyl;J;nders as a means for exploding thecharge, the spark tonobtaining this result be.- ing obtained in any wellknown manner com mon to devices oii this. class. An air inlet 7communicates with each of the cylinders on that side of, the piston inwhich the explo- {sion takes place, and this air inlet may be thecylinder. These valves are preferably located on the same valve shaftand occupy the relative P sitions illustrated in Figs. 3

,cylinder during the moveinent of, its piston. {under the force. ofexplosion. The valve Eshaft '12, to which the valves 10 and 11 areconnected, is of cylindrical form and has its. gpeater part practicallyof the same size as t e valves, as shown, indotted outlines in 5 Figs. 1and 2 of the drawing, that portion of Ethe shaft forming the. valveshaving ports }10" and 11, ascl early shown in Figs. 3 and 4 of thedrawing."

Itwill be. no erstood, of course, that the control the supply of airandof gas may a be. regulated'byasingle valve having pas :sages for theflow of air and gas. These vnueans tor controll ng said flow are soarranged that after the explosive charge is delivered from thecarbureter through the. inlet 5 into the gcylinder, and before the sparkis created tocause explosion. in that .i h ed ro s ex en menitcylinder,the' valve shaft rotates sufliciently ably. packed and each,- df thepistons maybe and 4, that is, bothvalvesare'OPBned to. each- W1res ortermi-.

. connected with any suitable source 013 air.

located preferably ber a to close the inlet 5, which inlet is closed atthe time the explosion takes place.

The admission of air from the tank 8 to the cylinder after the explosiontakes place, and the opening of the port 29, hereinafter referred to,causes matter extraneous to the explosive charge to be driven out at theend of the inward stroke of each piston.

The valve shaft 12 extends through the end of the valve casing and bearsa bevel gear 13 in mesh with a bevel gear 14 suitably mounted on anextension from the cylinder head. A gas valve lever 15 is secured to theshaft of the car 14;, and each end of the lever extends into the path ofmovement of the piston rods 3. It will be understood, of course, thatthese piston rods move in opposition to each other, and the lever 15 istherefore timed in its operations to admit the explosive charge from thecarbureter and air from the tank 8 at the proper time into each of thecylinders.

At the opposite end of each of the cylinders from that in which theexplosive charge is admitted and exploded is located a motor, as hereinshown, this including a turbine casing 16 in which a turbine 17 ismounted. A passage 18 leads from the chamber 19 in each of the cylindersto the interior of the turbine casing, preferably at the upper sidethereof and in position to conduct a liquid against thebuckets 20 of theturbine.

A reservoir 21 is located underneath each of the turbine casings, and apipe 22 extends its from each of the reservoirs to the chamber 19. Avalve 23 controls the passages from each of the pipes 22 into thechambers 19, and these valves are operated as by means of a drivingfluid valve lever 24 suitably connected to each of the valves. Smallrotary pumps 25 are located appurtenant to the pipes 22, these pumps 25being operated as by means of a' shaft 26 connected as by a belt 27 witha pulley on the shaft 28 of the turbine.

ln theoperation of the device thereservoirs 21 are filled with'a drivingfluid, as oil, and this is introduced by the action of the pumps 25 intothe chambers 19 of the cylinders. g 1

The operation of the device is as follows: The parts being. in theposition shown in Figs. 2, 3 and 4 of the drawing, and the piston in theleft handcylinder (the upper cylinder shown in 2) .having juststartedits inward movement, the valve 23 is im-' mediately closed as shown inFig. 3, and before the piston in the left hand cylinder has 0 scarcelymoved. The valves 10 and 11 are in position to close the openings intothe left hand cylinder. As the piston in the left hand cylinder travelsinward the valves 10 and 11. are rotated in a clockwise direction'asviewed from the right hand of Fig.

2. this causing the upper edge of the valve morass as seen-in Fig. 3 tomove to theleft. This movement opens the passages 5 and 7 to the lefthand cylinder permitting the explo-- sive charge to efiter, and as thepiston reaches the extreme forward limit of its movement the air fromthetank 8 is permitted to enter and blow out the extraneous matter aheadof the explosive charge. When the piston in the left hand cylinder hasreached this limit of its inward movement the explosion take place inthe right hand. cylinder efiecting the same operation of the parts withrespect to that cylinder as above described e v It will be understoodthat the explosive mixture is treated in the carbureter in a manner wellknown to devices of this class. It will be obvious that the lever 24:may, if desired, be operated by-mechanism differently constructed fromthat herein shown, and I do not desireto limit myself to the details ofconstruction in this respect;
